Azden's Zoom Shotgun Microphone for Camera and Mobile Devices is a high-performance shotgun microphone with wide and narrow pick-up settings. Use "Long" to focus on your sound source or pick up sound from a distance. Use "Short" for when your sound source is close or covers a broader field. Both settings will provide rejection of unwanted sound from the sides and the back. It is ideal for DSLR cameras, mirrorless cameras and mobile devices using the included TRRS adapter cable.
